The present invention includes compounds and compositions known to modify the perception of bitter taste, and combinations of said compositions and compounds with additional compositions, compounds, and products. Exemplary compositions comprise one or more of the following: cooling agents; inactive drug ingredients; active pharmaceutical ingredients; food additives or foodstuffs; flavorants, or flavor enhancers; food or beverage products; bitter compounds; sweeteners; bitterants; sour flavorants; salty flavorants; umami flavorants; plant or animal products; compounds known to be used in pet care products; compounds known to be used in personal care products; compounds known to be used in home products; pharmaceutical preparations; topical preparations; cannabis-derived or cannabis-related products; compounds known to be used in oral care products; beverages; scents, perfumes, or odorants; compounds known to be used in consumer products; silicone compounds; abrasives; surfactants; warming agents; smoking articles; fats, oils, or emulsions; and/or probiotic bacteria or supplements.
The invention is concerned with a process for the manufacture of substituted furans which are, in particular, flavorants; thereby 4-hydroxy-2-yn-1-ones or acetals or ketals thereof are cyclized with nucleophilic S-compounds to 3-S-furans, whereby this 3-S atom can be optionally substituted, and the acetylene derivatives, the 4-hydroxy-2-yn-1-ones, can be optionally 1- and/or 4-alkyl or alkenyl substituted.
Novel 3-sulfur derivatives of furan including alkyl furan-3-thiols and bis(alkyl-3-furyl) sulfides and di- and tetrahydro derivatives thereof having meaty and/or roasted aromas and flavors; processes for producing such 3-sulfur derivatives; novel flavoring compositions containing such derivatives; and novel food compositions containing such derivatives.
The present disclosure relates to compounds which are useful as cooling sensation compounds.

The invention relates to a process for the preparation of a savoury flavour which comprises reacting mono- and/or di-methyl-3(2H)-furanone or precursors thereof with cystein and/or hydrogen sulphide. Suitable precursors of mono- or di-methyl-3(2H)-furanone are oligomers of diacetyl, pyruvic aldehyde, pyruvic acid, acetoin, acetol, ethylene glycol aldehyde and glyceraldehyde, including mixed oligomers. The reaction is preferably carried out with cystein and hydrogen sulphide. The latter may be obtained before or during the reaction from a hydrogen sulphide donor.
The reaction is preferably carried out at pH below 7, at 60-160°C for 0.5-4 hours. A food grade acid such as acetic acid may be present.
The reaction mixtures obtained are rich in methyl substituted furanthiols or derivatives thereof.
The invention also relates to flavour precursor mixtures which generate a savoury flavour upon heating and comprises a mono- and/or di-methyl-3(2H)-furanone and/or precursor thereof, cystein and optionally a hydrogen sulphide donor.
